Passenger car and truck

From Kutna Hora left at 11:00 clock a truck at 60 km/h. At 12:30 behind him started passenger car at average speed 80 km/h. At what time and how far from Kutna Hora overtake a passenger car truck?


t = 17:00 Wrong answer
s =  360 km


s = 60(t-11)
s = 80(t-(12+30/60))

s-60t = -660
60s-4800t = -60000

s = 360
t = 17
